- The region of southeastern Washington and adjacent Idaho that has rolling hills on deep soils is known as the Palouse. On its eastern border, this region is bounded by the forests of northern Idaho, and the Snake River forms its southern boundary. To the north and west, the Palouse is bounded by areas of flat terrain and shallow soils, places where the deep soils were scoured away by ice or water during past glaciations or floods. Some scientists use a more inclusive definition of the Palouse; they consider areas to the west and south and even parts of northwestern Montana to be part of the Palouse.
- Alfred A. Plummer and Charles Bachelder settle on the site of future Port Townsend on April 24, 1851. (historylink.org)
On April 24, 1851, Alfred A. Plummer (1822-1883) and Charles Bachelder land on a beach at the mouth of Port Townsend, an extensive bay at the northeast corner of the Olympic Peninsula in what is now Jefferson County. They immediately file land claims and begin building a cabin. Plummer and Bachelder are the first non-Indians to settle in the area called Kah Tai by the Clallam Indians whose land it is. Six months later they join with two newer arrivals, Loren B. Hastings (1814-1881), and Francis W. Pettygrove (d. 1887) to establish the new town of Port Townsend, which they name for the bay.
